Abstract
The utility model relates to a gas-liquid separator in chemical fiber production equipment. The gas-liquid separator comprises a hollow body assembly and an outer wall condensation mechanism, wherein the hollow body assembly is provided with a liquid outlet (1) and an air inlet (14) at the bottom and an air outlet (9) at the top. The gas-liquid separator is characterized in that the hollow body assembly is internally provided with a first gas-liquid separation mechanism and a second gas-liquid separation mechanism in sequence from bottom to top, the double mechanisms can ensure that the flow direction of the introduced mixed gas containing liquid drops is continuously changed under the action of the outer wall condensation mechanism, and thus, a sixth-level defogging effect is taken. The gas-liquid separator is applied to the production of a high-performance polyethylene fiber and is simpler in installation and maintenance, simple and convenient to operate and capable of effectively solving the separation problem of an organic solvent in cooling air; the content of the organic solvent in the separated air is lower than 50ppm; and the requirement on a production process is met.
Description
Technical field
The utility model relates to a kind of gas-liquid separator, especially is applicable to the gas-liquid separator that uses in the high-performance polyethylene fibres production process, belongs to chemical fibre production equipment technical field.
Background technology
Usually, adopt a large amount of solvents when configuring the spinning slurry in the high-performance polyethylene fibres production process, and in spinning process, solvent is mainly overflowed from tow with gaseous form and is present in the spinning cooling air, for reducing solvent consumption, keeping the normal production order, is generally that organic solvent and spinning cooling air are recycled, and this separates the organic solvent in the spinning cooling air with regard to requiring.Comparatively common gas-liquid separator mainly contains spiral-flow type, rotary vane type, screen type.After rotational flow type gas-liquid separater mainly tangentially entered by gas, the effect by centrifugal force made oarse-grained liquid particle and barrel collision reach separating effect.The rotary vane type gas-liquid separator is by the inner barrel blade, makes gas flow by the air-flow that axially makes several bursts of rotations into, utilizes the effect of centrifugal force to reach centrifugation, and its separating effect is better than the spiral-flow type, but can only separate the bulky grain liquid particles.The screen type separator is flutterred to catch to the liquid state in gas by the metal steel wire on silk screen and is played separating effect, and relatively its gas-liquid separation effect is better with front two classes.
Above-mentioned three kinds of gas-liquid separator ubiquity following problems: be only suitable for the gas demist of bulky grain drop containing large amount of liquid amount, do not reach that in the high-performance polyethylene fibres production process, gas contains the liquid requirement, for containing the less mist of granule drop and content, its gas-liquid separation effect is relatively poor, the liquid particles that gas is carried secretly is more, and disposal ability is little.
Summary of the invention
The purpose of this utility model is to solve the problems of the technologies described above, and providing a kind of also has the gas-liquid Wireless Router of good gas-liquid separation effect for containing the less mist of granule drop and droplet content, to adapt to the production requirement of high-performance polyethylene fibres.
Technical solution of the present utility model is:
A kind of gas-liquid separator, comprise a ducted body assembly, be opened in described ducted body assembly bottom leakage fluid dram, be opened in described ducted body assembly top the gas outlet, be opened in the air inlet of described ducted body assembly bottom, and the outer wall condensing mechanism, be characterized in: in described ducted body component internal, be provided with successively the first gas-liquid separation mechanism and the second gas-liquid separation mechanism from bottom to top.
